Sand-removing seat belt buckle

Abstract

A sand-removing seat belt buckle has a housing and a latching assembly. The housing has a chamber, a first opening and a second opening formed through two ends of the housing, at least one sand cavity formed through a bottom of the housing and being adjacent to the second opening, and at least one support bump formed on an inner bottom of the housing. The latching assembly serves to latch and unlatch an insertion member, and is securely mounted in the housing and on top of the at least one support bump, so that a space is formed between the insertion member and the inner bottom of the housing and communicates with the first opening, the second opening and the sand cavity. Sand, mud and crushed pebbles entering from the first opening can be removed from the sand cavity and the second opening through the space without being deposited inside the seat belt buckle.

What is claimed is: 
     
       1. A sand-removing seat belt buckle, comprising:
 an insertion member; 
 a housing being hollow and having: 
 a first opening and a second opening respectively formed through two ends of the housing; 
 at least one sand cavity formed through a bottom of the housing and being adjacent to the second opening; 
 at least one support bump formed on an inner bottom surface of the housing; and 
 a latching assembly serving to latch and unlatch the insertion member, securely mounted in the housing and on a top of each of the at least one support bump, defining a space between the latching assembly and the inner bottom surface of the housing to communicate with the first opening, the second opening and the at least one sand cavity, and having; 
 a frame having:
 a bottom board having; 
 
 a sand-removing hole formed through the bottom board; and 
 at least one positioning hole formed through the bottom board and respectively corresponding to and aligning with the at least one support bump of the housing so that the bottom board is mounted on top of the at least one support bump through the at least one positioning hole; 
 two walls respectively formed on and protruding from two sides of the bottom board, each wall having: 
 a notched track formed in a top edge of the wall; and 
 a guide slot formed through the wall; 
 a fixing seat having: 
 a base mounted on the frame, and having: 
 a mounting cavity longitudinally formed through the base; and 
 an abutting portion; 
 an ejector formed on and protruding upwardly from one end of the base adjacent to the second opening, and movably mounted in the mounting cavity of the base; and 
 a first spring mounted in the mounting cavity, wherein one end of the first spring abuts against one inner wall of the mounting cavity of the base facing the first opening, and the other end of the first spring abuts against the ejector; 
 a latching member mounted on one side of the fixing seat facing the first opening, and having: 
 a bottom seat, wherein two opposite ends of the bottom seat are respectively and swingingly mounted through the walls; 
 a latching block formed on one edge of the bottom seat facing the second opening, and having a descending slope from one end of the latching block adjacent to the second opening to the other end adjacent to the first opening; 
 an ejector arm formed on and protruding upwardly from the edge of the bottom seat facing the second opening; and 
 a second spring mounted between a bottom of the bottom seat and the frame; and 
 a press button mounted through the first opening and on the frame, forming a tongue insertion space between the press button and the bottom seat of the latching member, and having: 
 a button body having: 
 two sliding bars parallelly formed on and protruding from one end of the button body facing the second opening, one of the sliding bars having a slanted surface formed in an outer sidewall of the sliding bar and having an ascending slope from one end of the slanted surface adjacent to the first opening to the other end adjacent to the second opening, and slidably mounted in a corresponding notched track; and 
 two secure portions, each secure portion formed on a junction on a periphery of the press button and between the button body and one of the sliding bars, and slidably mounted in a corresponding guide slot; and 
 a third spring mounted between the button body and the abutting portion of the base of the fixing seat. 
 
     
     
       2. The sand-removing seat belt buckle as claimed in  claim 1 , wherein the abutting portion of the fixing seat has at least one sand hole formed through the abutting portion of the fixing seat. 
     
     
       3. The sand-removing seat belt buckle as claimed in  claim 1 , wherein the housing has a bottom cover and a top cover correspondingly mounted on the bottom cover. 
     
     
       4. The sand-removing seat belt buckle as claimed in  claim 2 , wherein the housing has a bottom cover and a top cover correspondingly mounted on the bottom cover.
